Be it known vthat '1, Jesse J- Monscn, citizen of the United States, residing at Douglas,-- in. the county. of Converse and State of Wyoming, have inventedcer'tam new and useful Improvements in Shock Ab.-

Closing the cesinqat the open end thereof Iisa removable e'nd p ete16 detachably secured in position by'a plurality of cap bolts 17 and arranged within the casing ise rotary abutment l8,

At one side, the abutmentis rovided with a stud-I9 journaled in a su'itab e socket in'the end wall 11 of the casing and extending from I the abutment at its op osite'side is a spindle 20. Fixed upon the p ate 16 to surroundthe spindle is a bushing 21 journaling the spin le'snd screwed u on-siiid bushing is ighmd 22'forthe spin 1e. Formed in the spindle' axially thereof is a. bore 23 extending-;

Serewedjnto the bore 23 of the spindle 20; is a rod27 which maybe. -ed-- j usted toward the-outer end I of the 'pesselge 24 across the'p'assege-Qli so thatthe rod will thus function as a valve; tofcontrolffiow' of v .fiuid through said passages fend screwed" upon the outer end of'therod is a look but i? 28 for securingtherod,inadjusted .os i, ti"on,

Formed-.-

in the abutment in "advance of; the outer end of the passage 26 is. a radial slot 33 'and v slidably fitting in','said 'slot is ablede 34' which is somewhat-Jess in width than the 5 blade 30 end has its outer edge beveled in a. v direction opposite to the' bevel" of the outer edge of the latter blade, Arrn iiged behind r the blade Stare springs 35 compressing the; {1 9 vblede'outwardly into engagement with the} wallof the casing and formed through the:

blade is, as shown in detail in Figures ,5 and; ,1

6, a medial bore freely accommodating a r stop screw 36 threaded into the bottom wall. 1

of theslotBB end'having the headthereoifl countersunk in the-outerend of said bore- It is now to be noted that the abutment 18 is eccentrically "mounted within the casing 10 to contact. the wall of thecasing atone side thereof so thatat the oppositeside of the casing, a chamber e7 is defined between of the abutment- 1s a passage 25 70 i seal the casing. v

of the casing to enter the chamber 38 is an air escape opening 41- normally closed by a plug 42. Thus, by removing the plugs 510 and 42, the casing may be filled with a suit- -able fluid such as glycerine when, of course,

the plugs are again arranged in position to Fixed to the outer end of the spindle is an arm or crank 43 having a ball head 44 and straddling the spring 14' is aclip 45 secured to the axle 15 and equipped at its upper end with an arml6 having a ball head 47. Extendingbetween the ball-head 44 of the crank 43 and the ball head47 of the clip is a link 48 provided at its ends witlr'sockets 49 to accommodate said heads andscrewed into said sockets are plugs 50'adiustable to secure the desired tension betweenv the sockets and the ball heads.

' As will now be readily understood, when the spring 14 of the vehicle is compressed, the abutment 18 will be rotatedin'a; clockwise direction, when the fluid in the chamber 37 will wedge past the beveled outer edge of the, plate 30 and will thusbe allowedrto freely flow from the'chamber -37'into the in the chamber. 38 is compressed, the fluid chamber 38. Ho wever, upon return move-.

ment of the spring, causing the abutment to be rotated in a counter-clockwise direction, the flow of fluid from the chamber 38 to-the chamber 37 will beblocked by the blade30 so that as the rotation of the abutment continues and the blade is advanced, the fluid in the chamber 38 will be trapped and comressed for resisting the counter-rotation of the abutment and'accordinglv resisting the return movementof the vehicle spring. The blade 34 is, of course, provided to form a seal between the abutment and casing in advance of the passage 26 so that as the fluid will enter through the passage 32 to the slot. 29 behind the blade 30 for forcing this blade outwardly againstthe w'all of the casing to maintain a sealed joint between. the blade 30 and the casing while the fluid will also enter through the passage 26 to the passage.

24 and thence through the passaa'e25 to the chamber 37. Flow of fluid through the passages 24, 25 and 26 will. as noted, he regulated by the valveor rod 27, .which mav be set to suit the tension of the springs of the particular motor vehicle to which the device is applied so that the device will thus function to cushion the return movement of the springs and permit only an easvan'd gradual reboundof the vehicle body. In this connection, it is to be observed that during the counter-rotation of the abutment 18, displacement-of fluid from the chamber 38 will'grad- (will taper froma'maximum' at the inception of the couuter rotation toward 'a minimum as -the.- counter-rotation progresses. Accordingly,'\vhcn the springs of the vehicle are compressed and are, therefore, under greatest'tension, thedevice will offer the greatest resistance to the return movement of the springs and this resistance will tap'er gradually in conformity 'u'ith the return flexing-of the-springs and the relief of tension thereon; Thus, regardless of the degree to which the vehicle springs may be compre sed. the device will always, function properly'to offer a corresponding core'lated resistance to the return movement of the springs for rendering such return movement easyr and gradual. -The stop screw 36-is provided to limit the outward radial movement of the blade 34' in order that, when the abutment is counterrotated, too great'a volumev of fluid may not be trapped in front of the blade Furthermore, said stop' screw 'will prevent' the "complete ejection of the blade from its slot should the abutment, for

anYreason, be completely revolved. Having thus described the mventlon, what is claimed-as new is:
